The invention provides an implanting and sinking platform of a concrete precast pipe pile for an overhead transmission line. The implanting and sinking platform comprises a hole digging device for digging a pile sinking hole in the ground, a side hole digging device for punching the side wall of the pile sinking hole, a pressure device for applying pressure to cement mortar poured in the pile sinking hole, and a pile sinking device for lifting the precast pipe pile. The invention further provides an implanting and sinking method of the precast pipe pile. Through the implanting and sinking platform and method, the friction force between a transmission line tower pipe pile and the ground can be increased, the installation quality of the pipe pile during sinking is improved, and the installation speed of the pipe pile is increased; and the wind resistance and the shock resistance of a tower are greatly improved, the resistance to natural disasters is improved, and losses caused by the natural disasters are decreased.
